    Reland of Amend DataView, ArrayBuffer, and TypedArray methods to use ToIndex. (patchset #2 id:170001 of https://codereview.chromium.org/2113593002/ )
    
    Reason for revert:
    WebGL tests have been updated and rolled (at https://codereview.chromium.org/2227023002), so this should no longer fail outdated tests.
